PRESSINGr-IRON.

Specification of Letters Patent.

Patented Nov. 1, 1921.

Application filed Au ust 21, 1918. Serial No. 250,877.

To all whom it may concern:

Be it known that I, HERMAN W. PETE, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Pressing- Irons, of which the following is a specification.

The present invention relates to pressing irons and more particularly to the type in Which a steam chamber is provided within the iron body for heating the iron, and a plurality of steam escape openings is provided in the bottom of the iron pose of m'oistening the surface to be pressed, suitable means being employed for controlling the escape of steam through the openings from the steam chamber.

An object of this invention is to provide an inexpensive construction in which the controlling means is simple in operation and not liable to get out of order and the operating parts are subject to ready repair.

To these and other ends the invention consists of certain parts and combinations of parts, all of which will be hereinafter described, the novel features being pointed out in the appended claims.

In the drawings Figure 1 is a vertical section through an iron constructed in accordance with this invention;

Fig. 2 is a detail view of the valve operating devices;

Fig. 3 is a detail view of the valve; and

Fig. 4 is a vertical section on the line t4, Fi

The present application disclosescertain features which are also found in an application filed by me on June 13, 1917, and to these features the present application is a division of said application.

In the illustrated embodiment of the in: vention, 1 indicates the iron body formed from a single casting with a steam chamber 2 into which steam is delivered by an inlet 3. The latter in this instance is in the form of a pipe extending from the rear wall of the body to a point near the front end of the body and situated in spaced relation to the bottom of the chamber. An outlet for the steam is provided in the rear wall and is situated at a point slightly below the bottom of the chamber so that water of condensation may readily pass from the steam chamber.

An additional'chamber 5 is provided withfor the par-- 1n the iron body, this chamber preferably being elongated and extending nearly the full length of the chamber 2, its ends being deflected upwardly at 6 and through the top of the iron Where such ends are closed by plugs .7. The purpose of I her 5 withupwardlyextending ends is to permit the formation of said chamber in the casting operation. The chamber .5 has its upper wall abovethe bottom wall of the chamber 2, and its lower wall below the bottom wall of the chamber. Fins or lugs 8 may be projectedfrom the top wall of the chamber 5 into the chamber 2 and the bottom Wall of the chamber 2 may likewise have such upwardly-projecting fins for the pur-' pOse of conducting heat to the bottom of the iron. From the chamber 5 a plurality of perforations or openings 9 extend through the bottom wall of the iron body, in order to permit steam to pass from the chamber 5 through the bottom face of the iron for the purpose of moistening the goods which are to be pressed. These openings are preferably comparatively small and the series extends in a line longitudinally of the iron.

Steam is admitted into the chamber 5- from the chamber 2 by a port or opening 10, which, in this instance, is formedeccentrically within a plug 11 fitted by screw threads thereon in a larger opening in the top of the chamber 5. This plug 10 may also have a central depression 12 in which one end of the valve stem 13 is fitted, said stem carrying, in this instance, a valve disk let 005perating with the plug 11 and provided with an eccentrically arranged opening 15 which maybe brought into register with the opening 10 in order to provide communication between the chamber 2 and the chamber 5. About the rotary plug 14 the plug may be provided with an upwardly-extending flange 16 which serves to center the valve 14 when the latter is being fitted to its seat on the plug 11, this flange having1 openings 17 through which water of condensation may be passed so that the water will not collect about the valve 14. The opening 10 being situated in the top wall of the cham her 5 and above the bottom wall. of the chamber 2, there is no tendency for any water of condensation to pass through the chamber 2 to the chamber 5. v

The iron is manipulated by a handle 18 which is held by a nut 19 on the upper tapered end of a handle stem 20. This forming the chamhandle stem has a removable steam-tight connection with the iron body 1, and to this end the lower end of the stem is provided with a screw-threaded portion 21 and a surrounding shoulder or abutment 22,. the screw-threaded ortion engaging within an internally-threa ed bore 23 in the top wall of the iron body 1 directly over the valve 14 and the plug 11, so that the valve and plug may be introduced through the opening 23. It is preferred to mount the valve 14 on the handle, and to this end the stem 20 has "a central bore 24 through which the valve stem 13 extends to project beyond the lower end of the handle stem 30 and to .carry the valve 14 on its projecting end.

Between the valve 14 and the lower end of the handle stem 20 a helical spring 25 may be arranged in order to maintain the valve 14 yieldingly against the seat on the top of the plug 11. The upper end of the valve stem 13 extends through a stufling box 26 at the upper end of the handle stem 20 and is provided with a laterally operating arm 27 This lateral operating arm is preferably held in position to close the valve 14, and to this end there is employed a spring 28 coiled about the projection 29 on the handle 18 and having an arm 30 hearing against a depending projection 31 on the valve stem arm 27. This spring arm 30 permits the handle-operating arm to be turned to a position where theopening 15 in the valve 14 may be brought into register with the opening 10 in the plug 11, so that communication may be established between the chamber 2 and the chamber 5. The iron as a whole may be supported by a bearing member 34 from a pressing machine of any suitable type, said bearing member surrounding the stem 20 and to thls end having a portion 33 formed with an opening 32. The portion 33 has a rocking bearing between two bearin blocks 34 held between the shoulder 22 an the lowermost portion of the handle 18.

In the use of the invention the steam supply is connected to the steam inlet 3 to supply steam to the chamber 2, the exhaust of said steam taking place by way of the outlet 4. This effects the heating of the iron bodyto a temperature suflicient to produce a pressing action without any danger of burning or scorching the goods. Should it be desired to moisten thegoods, the handle 27 is manipulated by the thumb of the user, and this effects the turning of the valve 13 to bring the opening 15 in the valve into registration with the port 10 in the plu 11, thus admitting steam to the chamber 5 rom which it exhausts through the openings or perforations 9 in the bottom or ironing face of the iron.

An iron constructed in accordance with this invention is very effective for pressing goods without scorching or burning. lhe

goods may be moistenedwithout sponging which tends to produce spots. The valve arrangement by which steam is conducted from the steam heating chamber to the steam exhausting chamber is of simple construction and not liable to get out of order, the valve being efl'ectively held to its seat by a yielding pressure while being readily movable to provide. communication between the chambers. The opening between the chambers is formed in the top wall of the steam exhausting chamber above the bottom of the steam heating chamber and, as a consequence, there is no danger of water of condensation assing into the steam exhausting chamber. This communication is situated directly below-an opening in the top of the iron body in which the handle is secured. The valve is mounted on the handle so as to be removable therewith, the spring which holds the valve to its seat having an abutment on the handle stem and removablewith the handle and the valve.
